To close out the show, Springsteen and the Band brought out Paul McCartney to play a rendition of "Santa Claus Is Comin' to Town" with Fey, Poehler, and the "SNL" cast, as Rolling Stone notes. Springsteen also tweeted a photo of himself backstage with McCartney.

Also in the "SNL" episode, hosts Tina Fey and Amy Poehler parodied Taylor Swift's star-studded "Bad Blood" video. Fey plays "Powderkeg" and Poehler plays "Shortfuse". They explain that they're able to have successful careers while managing families because of their "Dope Squad" of nannies, doctors, and friendly neighbors. "SNL"'s Aidy Bryant drops a guest verse (like Kendrick Lamar in Swift's video) and Amy Schumer makes an appearance, as well.
